Saunum Classic
A complete outdoor sauna, with or without a heater
The Classic pairs a compact Nordic cabin with a wide glazed front and Saunum's more even, air-mixed sauna climate. It seats three in comfort or four at classic sauna closeness.
The fixed cabin specification includes the black Thermo-pine exterior, full Thermo-Aspen interior, I-shaped bench, dimmable lighting, Bluetooth speakers, glazing, ventilation, rainwater system and protective transport box. Order the cabin on its own, or add one of two 9 kW Saunum heater sets in the customiser.
2.4 × 2.1 mCabin footprint
Up to 4Three in comfort
2.487 mExternal height
Included in the cabin package
The finish, lighting and practical systems are already specified
The Classic arrives as a coherent cabin rather than a list of paid finishing extras.
Layered dimmable light
LED strips sit behind the backrest and beneath the upper bench, giving the room a warm glow without harsh overhead glare.
IncludedBluetooth sound
Integrated speakers let you play audio without carrying a separate speaker into the sauna room.
IncludedBlack Thermo-pine shell
The exterior is finished in black Thermo-pine with hidden fasteners for a clean, contemporary face.
IncludedClear insulated glazing
Clear double-glazed glass keeps the front open to the garden and helps the cabin hold its heat, while the separate 8 mm tempered door adds a clean break without narrowing the view.
IncludedPrepared for the site
The electrical box, ventilation and rainwater system are already fitted, so there's less for your electrician to source or connect once the cabin's in position, and the OSB transport box keeps it protected until then.
Included
Warm timber, softer heat
A calm interior built around the way the room feels
Thermo-Aspen runs across the walls, bench, backrest, skirt and floor mat, so the room reads as one warm timber interior. Dimmable strips behind the backrest and beneath the upper bench add depth after dark.
If you add either Saunum heater, its patented system blends hot ceiling air with cooler floor-level air. The result is a more even climate from head to toe, with three airflow settings to tune the session.
I-shaped benchSeats three in comfort or up to four close together.
Dimmable LEDsWarm light behind the backrest and below the upper bench.
Bluetooth speakersAudio is built into the cabin package.
Air-mixed climateA more even temperature from head to toe.
The only choice
Add a 9 kW Saunum heater if you need one
The cabin can be ordered without a heater. If you add one, both sets include stones and the complete WiFi-enabled Saunum AirIQ control system; the difference is the heater design.
WiFi and in-sauna airflow control are included with either optional heater set. The touchscreen is fitted outside the sauna; the internal AirIQ button adjusts air circulation from inside the room.
Wide glass, compact footprint
An open garden view without giving up an insulated cabin
The clear double-glazed front brings daylight and the garden into the room while helping the cabin retain heat. A separate 8 mm tempered-glass door keeps the broad viewing panel visually uninterrupted.
Outside, black Thermo-pine with hidden fasteners keeps the structure quiet and architectural. Inside, the pale Thermo-Aspen and warm LEDs make a deliberate contrast.
Practical planning
Plan the base, access and electrics before delivery
The Classic travels as a large assembled unit. Its route into position matters just as much as the final base.
A fully supported base
Prepare a level, stable and well-drained base that supports every base beam and safely carries the approximately 1,250 kg cabin.
Mechanical unloading
The cabin arrives in an OSB transport box and cannot be handled like a normal pallet. Plan a suitable forklift, HIAB or crane for unloading and positioning.
A dedicated supply
If you add a 9 kW heater, it requires a dedicated electrical supply. A qualified electrician must confirm the protective devices, isolator, cable size and final connection.
Use the Request an Installation Quote link under Add to Cart if you would like Heracles to assess the access route, prepared base, positioning and commissioning work.

Saunum Classic in context
A clean black cabin with warmth behind the glass
The compact rectangular shell sits neatly beside a house, pool or garden room, while the wide front keeps the sauna visually connected to its setting.
Cabin-only or with a Saunum heater
Order the complete cabin, then add a heater only if you need one
Use the customiser above if you want to add a heater, or leave it unselected for the cabin on its own. For access, base or commissioning help, request an installation quote before ordering.

The Sauna of the Next Century
How Does Saunums 5-in-1 Patented Technology Work?
Saunum’s patented air-blending system traps the scorching steam, that rises under the ceiling of the sauna room, mixes it with cooler air on the floor surface, and directs the soft steam back evenly. This ensures a more even temperature of the steam, and the oxygen-enriched steam makes it easier to breathe. Water can be thrown more often to produce more steam, making the sauna air more humid, and ensuring more intense sweat. With Saunum’s patented method of enriching the air with salt ions, the salt ions from the natural salt spheres added to the sauna climate device are infused into the circulating air to reach the skin and respiratory tract. An even more relaxing sauna experience is created with the help of the aroma system, which mixes sauna oil aromas with the steam. It is a healthy alternative to burning aromatic oil on hot stones.
